So with the logic (and the addin) it says I need to defer, action etc...

However I have already created a project and or action in some cases which result in a THREAD of emails.

What I would like to do is

1) Send an email (assign it to a project)
2) Any replies to it, and intern my replies to be automatically linked to the first BECAUSE I assigned it. Another button called READ TO PROJECT would assign it.

This would allow me to track a smaller number of items, but expand them when required
